|Abstract:||In this paper, a new method of non-contact tool wear measurement is presented. It employs a phase shifting method using fringe patterns to measure crater wear by constructing a 3D map of the tool insert. Four fringe patterns with various phase-shifts are projected onto the rake face of the tool upon which four gray-level images are captured. By solving and then unwrapping the phase map with the four images, a 3D profile of the tool is obtained to provide the overall size of the crater wear land. Sample tool inserts with various crater wear surfaces have been evaluated with the method and the results demonstrate that the system is robust to ambient light and is accurate and applicable for use in real industrial environment to measure crater wear. © 2005 Elsevier B.V.
